Quality of life in older individuals with joint contractures in geriatric care settings.

PURPOSE: The purpose of this study was to analyze the association between functioning and disability and quality of life (QoL) in older individuals with joint contractures in the geriatric care setting. More specifically, this study aimed to identify determinants of QoL out of a defined set of contracture-related categories of the International Classification of Functioning, Disability and Health (ICF). METHODS: Participants for this multicenter cross-sectional survey were recruited from acute geriatric rehabilitation hospitals, nursing homes, and community nursing facilities in Germany between February and October 2013. QoL was assessed using the validated German version of the EQ-5D index score and the EQ-5D visual analog scale (VAS). Manual and automatic variable selection methods were used to identify the most relevant variables out of 125 contracture-related ICF categories. RESULTS: A total of 241 eligible participants (34.9 % male, mean age 80.1 years) were included. The final models contained 14 ICF categories as predictors of the EQ-5D index score and 15 categories as predictors of the EQ-5D VAS. The statistically significant ICF categories from both models were 'muscle power functions (b730),' 'memory functions (b144),' 'taking care of plants (d6505),' 'recreation and leisure (d920),' 'religion and spirituality (d930),' 'drugs (e1101),' and 'products and technology for personal use in daily living (e115).' CONCLUSIONS: We identified the most relevant ICF categories for older individuals with joint contractures and their health-related quality of life. These items describe potential determinants of QoL which may provide the basis for future health interventions aiming to improve QoL for the patients with joint contractures.

A pragmatic randomized controlled trial of thiopurine methyltransferase genotyping prior to azathioprine treatment: the TARGET study.

AIM: To conduct a pragmatic, randomized controlled trial to assess whether thiopurine methyltransferase (TPMT) genotyping prior to azathioprine reduces adverse drug reactions (ADRs). METHODS: A total of 333 participants were randomized 1:1 to undergo TPMT genotyping prior to azathioprine or to commence treatment without genotyping. RESULTS: There was no difference in the primary outcome of stopping azathioprine due to an adverse reaction (ADR, p = 0.59) between the two study arms. ADRs were more common in older patients (p = 0.01). There was no increase in stopping azathioprine due to ADRs in TPMT heterozygotes compared with wild-type individuals. The single individual with TPMT variant homozygosity experienced severe neutropenia. CONCLUSION: Our work supports the strong evidence that individuals with TPMT variant homozygosity are at high risk of severe neutropenia, whereas TPMT heterozygotes are not at increased risk of ADRs at standard doses of azathioprine.

A clinical characterization of familial keloid disease in unique African tribes reveals distinct keloid phenotypes.

BACKGROUND: This study is a clinical characterization of keloid scars in an African population comprising three rural tribes with familial keloids. Site distribution, morphologic features, and other characteristics of the scars were studied to assess whether each tribe had a specific scar phenotype. METHODS: Keloid scar clinics were set up at Soba Hospital in Khartoum, Sudan, for patient recruitment and management. In addition, familial keloid cases were recruited from rural tribal populations during field trips. A database including clinical and demographic data and digital photographs of all keloid cases was established. Statistical analysis was conducted using SPSS and SAS software. RESULTS: One hundred eleven individuals with keloid scarring (67 male subjects and 44 female subjects) were recruited. Patients were predominantly from three multigenerational pedigrees (total of 38 nuclear families) afflicted with keloid scars residing in different rural regions of Sudan. Two distinct morphologic phenotypes of keloid scarring were observed. The first phenotype has been designated "superficial spreading" (horizontal) keloid and the second has been designated "raised" (vertical) keloid. Clinically significant features and statistically measurable morphologic parameters were compared among these phenotypes (p = 0.001). Furthermore, linear claw-like extensions of keloid (transgression) were noted to be significantly higher in the superficial spreading keloid phenotype (p = 0.03). CONCLUSIONS: There is strong evidence of different phenotypes of keloid scarring. Two distinct phenotypes have been observed, described, and statistically verified. Each tribe demonstrated one particular phenotype, with two being superficial spreading and one being raised. Other significant clinical characteristics have been described. This is of significance in understanding both the clinical basis and the genetic basis of keloid scarring.
